We look at the division of 533519 by 86 
The aim is to understand the frequency of 86 in 533519.

Moving on to step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 86

Going ahead to step 2:
86 can be fit into 53 0 times, resulting in a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 86

On to step 3:
533 divided by 86 is 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 516 from 533 and we're left with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 86

Advancing to step 4:
If we divide 175 by 86, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we subtract 172 from 175, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 86

Let's proceed to step 5:
31 divided by 86 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 620.0
If we take 0 away from 31, we end up with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 86

Moving on to step 6:
86 can be fit into 319 3 times, resulting in a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 6203.0
Deduct 258 from 319 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
When dividing 610 by 86, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 6203.7
Subtracting 602 from 610 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
86 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 6203.7
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
800 divided by 86 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 6203.709
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
If we divide 260 by 86, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 6203.7093
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
When dividing 20 by 86, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6203.7093
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
200 divided by 86 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6203.709302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 86 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 6203.7093023
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
The number 86 fits into 220 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 6203.70930232
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 6203.70930232, and the remainder is 4.8e-08.
